Title: Information input device of camera
Inventor: NAGATA TOORU
IPC: G03B7/24
Filed: 1983-11-11
Abstract: PURPOSE:To clean the contact part of a contactor and to reduce the contacting pressure of the contactor by providing a protection meber which moves the contactor to a protection and an exposure position according to photographing operation. CONSTITUTION:The protection member 4 which protects the contactor for information input provided at the side of a camera body 1 is moved between the protection position A and exposure position B associatively with the opening and closing of a rear cover 6. When the rear cover 6 is open, the contactor which reads information from the flank of a cartridge P is protected by the protection member 4 at the protection position A, so the contactor 3 is not touched directly with a hand. When the rear cover 6 is closed and a film is taken up by one frame, a driving mechanism moves the protection member 4 from the protection position A to the exposure position B and the contact part of a contact piece 3 is cleaned by an abutting surface 4b sliding on the contact piece 3, so the contact pressure of the contact piece 3 during the loading of the cartridge P may be small.

Title: Damper mechanism
Inventor: OSHIMA KAZUYOSHI
IPC: E05F3/14
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent fluid in a high pressure chamber from flowing out to a low pressure chamber side by forming a projection part which is projected in a circumferential direction and which is elastically deformable in an diameter direction, on the top end part of a side surface faced to the high pressure chamber of a bulk head part partitioned an enclosed space into the high pressure chamber and the low pressure chamber, in a suitable damper mechanism using in a door closer and the like. SOLUTION: A damper mechanism 5 for a door closer consists of a pressure generating part 6 and a pressure control part 7, a valve body is rotated by fluid in a low pressure chamber SL when a door is opened and a casing 61 is rotated, the valve part is apart from a housing hole, and thereby, a high pressure chamber SH is communicated with the low pressure chamber SL. When the door is closing operated, the housing hole is shut out by the valve part go as to generate damper effect. In this case, a nearly semicircular recessed part 61e is formed on the side surface of a bulk head part 61c faced to the high pressure chamber SH, and a projection part 61d which is projected in a circumferential direction is sectioned on the inner circumferential side end part of the side surface.  The projection part 61d is brought in contact with an axis body 44 in an elastically deformed condition so as to improve fluid-tight properties between the bulk head part 61c and the axis body 44.

Title: Induction heater
Inventor: NOMA HIROBUMI
IPC: A47J27/00
Filed: 1988-08-25
Abstract: PURPOSE:To prevent mis-energizing of a switching element and destruction thereof by keeping the switching element on an off only for a time from turn-on of AC power until an output voltage of DC power circuit reaches a normal operation voltage of a control circuit. CONSTITUTION:When an AC power is turned on, the drain source voltage VDS of a switching element 10c rises and then, an output voltage VCC of a DC power circuit 12 rises behind VDS. A gate source voltage VGS of the element 10 begins rising in a period of time for which VCC does not reach a voltage at which a control circuit 11 works normally. However, when VGS reaches such a voltage that a base current can be supplied to a transistor Tr 13f of a protection circuit 13 through a resistor 13d, the Tr 13f conducts so that VGS never rises up higher than that voltage. If a control voltage is set lower than the threshold voltage of the element 10c, the VGS of the element 10c does not exceed the threshold voltage, so that it is possible to prevent misenergizing of the element 10c and its destruction.

Title: Estimation processing method for two-dimensional movement field
Inventor: TAKEGAWA NAOKI
IPC: G06T7/20
Filed: 1989-08-16
Abstract: PURPOSE:To obtain an accurate 2-dimensional movement field by computing repetitively the general evaluation value to optimize it and detecting a movement vector on a 2-dimensional screen. CONSTITUTION:A 2-dimensional movement field/luminance difference/variable arithmetic circuit 7 corrects the 2-dimensional movement field, the luminance difference, and the variable based on the luminance gradient value and the 2-dimensional movement field/luminance difference/variable data received from a 2-dimensional movement field/luminance difference/variable memory 6. An evaluation value arithmetic circuit 8 calculates the evaluation value based on the gradient value obtained from a gradient arithmetic circuit 5 and the values of the 2-dimensional movement field, the luminance difference, and the variable. Then a latch 9 inputs the values of the 2-dimensional movement field, the luminance difference, and the variable and outputs the 2-dimensional movement field/luninamce difference/variable data, i.e., the final arithmetic result via a movement field/luminance difference/variable output terminal 11 in response to the timing signal received from the circuit 8. Thus it is possible to obtain a highly accurate 2-dimensional movement field even to a real picture having the shadow.

Title: Comparator holding circuit
Inventor: MEGURO TOSHIYUKI
IPC: H03K5/02
Filed: 1986-09-10
Abstract: PURPOSE:To reduce the number of parts and to improve the reliability of the titled circuit by forming an one-way characteristic feedback circuit having light emitting characteristics for feeding back a part of an output signal to a non-inversional input terminal between the output terminal of a comparator and its non-inversional input terminal for inputting an input signal. CONSTITUTION:A light emitting diode and the cathode side of a diode 3 are connected to the output terminal of the comparator 1. The threshold of an input voltage to be held is determined and the threshold voltage VSH is impressed to the inversional terminal of the comparator 1. When an input voltage VIN and the threshold voltage VSH are impressed to the comparator 1 and the input voltage VIN exceeds the threshold voltage VSH, the output voltage VOUT of the comparator 1 is almost equal to the supplied power VCC of the comparator 1. Since the output voltage VOUT is impressed to the non-inversional input terminal of the comparator 1 through the light emitting element 2, the comparator 1 can hold the output voltage VOUT for a long period. Thereby, the number of parts, price and reliability can be sharply improved as compared with an ordinary holding circuit constituted of transistors, relay and so on.

Title: Ophthalmic examination device
Inventor: OKINISHI SATORU
IPC: A61B5/026
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To make re-measurements without tosses without impairing the effectiveness of simultaneous measurements of blood flow velocity and blood vessel diameter. SOLUTION: An angiogram received by a one-dimensional CCD 42 is displayed on a display means 55 as the waveform of a light reception signal of the one-dimensional CCD 42 to determine whether or not measurement data are permissible. If this evaluation result shows that the blood vessel diameter information measured is not good, a data re-measurement setting means 49 is operated. Thereby a system control part 47 deletes the corresponding blood vessel diameter information in a file from a storage means 53 and converts a measurement sequence into the state of measuring only the blood vessel diameter information.  When measurements of the blood vessel to be examined are made again as usual, emission of light from a laser diode 36 is stopped via a light source control means 52 and only tracking beams are irradiated to the blood vessel to be examined to sample blood vessel shape information. The newly obtained light reception signal of the one-dimensional CCD 42 and the blood vessel diameter information are added to the file at the same time that the measurements are finished with the irradiation stopped.
